Krumm attended Natrona County High School, located in Casper, from which he graduated in 2005. He studied electrical engineering at Colorado School of Mines. Whilst taking a class in Casper College, his calculus teacher Mickie Goodro remembered him as being one of the smartest students she'd ever had "but his social skills were not wonderful."
He was diagnosed with Asperger syndrome in high school, and claimed to have inherited the condition from his father. Allegedly, he had been gravely troubled by his condition, blaming it for the reason he could not hold stable jobs. once stating that his father should be “castrated” to prevent him from passing it onto others. Three years before the attacks, Krumm and his father had a falling out. James Krumm claimed that Christopher hated him, blaming for inheriting his condition.
Christopher Krumm resided in Vernon, Connecticut and worked as an engineer. Just six weeks before the murders, in mid-October, he applied for a handgun license, which is required to possess or carry a handgun in the state of Connecticut. For unknown reasons, Christopher did not wait for his license to come through, and carried out his attack while the aforementioned paperwork was still being processed. Firearms were not used in the attack.
